Among the global coal geological systems, the char-acteristics of coal geology in China are both globally comparable and unique. The formation periods of China's coal-bearing processes were basically consistent with the main global coal-forming periods, although they differed in the sizes and intensity levels of their coal deposits.
Like all fossil fuels, global coal reserves are very unevenly distributed. Text Version The UK and Europe were fortunate in having extensive coalfields that powered the Industrial Revolution.

The distribution of worldwide coal deposits is uneven, which is the result of peat formation at different times in the geological record in predominantly tropical latitudes and the subsequent drift of the continents to their present-day positions. The major regions with coal deposits are located in the Northern Hemisphere, whereas the regions in the Southern Hemisphere, with the exception of ...
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Tertiary coal deposits which are around 55 million years old. Tertiary coal deposits are found in the North-Eastern states of Meghalaya, Assam, Arunachal Pradesh and Nagaland.
